Science Daily  May 22, 2024 High-aspect-ratio mechanical resonators are pivotal in precision sensing. However, fabrication challenges and high computational costs have limited the length-to-thickness ratio of these devices. An international team of researchers (The Netherlands, USA – Brown University) developed nanomechanical resonators that extend centimeters in length yet retain nanometer thickness. They expanded the design to include more computationally intensive centimeter-scale design optimization. Their approach ensured high-yield realization, experimentally confirming room-temperature quality factors close to theoretical predictions. According to the researchers synergy between nanofabrication, design optimization guided by machine learning, and precision engineering opens a solid-state path to room-temperature quality […]
